Hospital has instituted a new rate system. Local pricing and a special "out of town rate" (3x-5x the locals rate) <img src="http://www.traveltalkonline.com/forums/images/graemlins/Yikes.gif" alt="" />.
That's why I don't travel there without AirEvac/Medical insurance. I think it cost me $130 for 2 weeks, worth it for the peace of mind and also because your insurance (US) will probably only pay "out of network" rates. My insurance broker also mentioned that if you ever get treatment out of the country, be sure the hospital/provider designates it as "emergency treatment" or you'll have a long row to hoe trying to get reimbursed(at in or out of network rates) these days.
